.To azzwhom a may concemi Be it known that LED ARD Gonrnn I Pittsburg,- in the county of Alleghenyand a view of a'portionof the wall;- Fig. 4'is a ver- State of Pennsylvania; have inventeda certain new and usefu'll'mproyement .i'n" Rein- :one of. the ribs orpounterforts of the we Fi -i2 i's'a rearelevation of a portion of the dotted linesyFig 3 Ilsa-horizontal sectional tieal sectional view of a man time mu;

provide for pressure greater'than that which might ordinarily beexerted.

To this 'end my invention consists in reinforcing; rods secured to anchoring bars or plates embedded in a counterfort, which rods l 4 and plates act to tiethebottom slab and ver- .tical walls together; and make a connected 1. will now d s myripventiw mains may emplo thesame.

slab of the wall and 3 the front "curtain wall.

Above the slab. Zarethe steps 4,- the-purpose of whichis to obviate steel rod reinforcement to the slab in this portion. At} desired intervals, extending rearwardly from the wall 3 .are' the counterforts 5, the outer faces of- 'zonta which slolpe at an angle-from the end of the base of t e slab 2' to the top of the curtain wall 3. "These to be formed '0 thesteel framework of the wall is erected; This steel framework is composed...-of vertical or approximately vertical ang pp or ppfoximatelyuhorizontal angle parts of the wall are'designed a bars; and tie secured to the angle-bars or plates.

t tien being indicatedby" and Fig.7,5 is a horizonta sectional-view of a portion of the wall illustrating a modification.

-My invention. relates to" an. improvement m reinforced concrete retainingwalls adapt- I that feelers skilled in the a rt' ---.t. 'w i1 I the drawings; 2 representsf tli e bottom\ are,v horiconcrete to be filled'in after are extending between and wall to the top thereof. These vertical-bars are'located at each "of the. counterforts 5.-

In'the drawings-6 represents, the vertical angle-bars .01 plates,- located in the curtain of thewalland extending from the basejof this Y Extending horizontally, orat an angle to the vertical barsgfi are Panglebars or plates .7.

The bars 6. a1id7 may beunit-ed at their adj ac'ent or-meeting ends by suitable boltsor' other attachments; The flanges'of the anglebars 6 and (are provided with'holesthrough which pass the" ends of: the round tie-bars 8, which ends are-threaded and secured to. the angle-bar by the front and back nuts 9 and 10, or byother. suitable attachments. These rods 8- may 'startrvertically, but begin near thefoot of the wall' to curve and thence exing at a.- oint adjacentto thesebars so asto' enter he esin the flange of the. bar 6 atsub." stantially' right"-arng-lei to" the vertical. plane :of-thesame. 'lhe'upper ends of'the. rods 8 are threaded and-arez'secured to the flange of the vertical bars 6 by front and back nuts 9- and 10, -or' by other suitable attachment.

Horizontal rods 12fp'ass through the second fl e of the vertical bars 6, and serve as a rei orcement to the curtain'wall. They may besecured-by double nuts at. the two end bars, similar to. the two nuts 9 and 10. A Similar horizontal bars 14 pass through the fi es of the horizontal bars 7', and they may e secured-in a like manner as in the case of the rods 12. InF'g; 5 a plate or bar '15 and devices 16 for securing the end of the tie-rod 17 tojthe anchgr-baror. plate. This device may be usedin place of either the horizontal-or vertical angle-bars 6 and 7, but I do not desire. to limit myself to any specific form ofanchoring bar-l.

The advantages of 'myinvention will be appreciated by those skilled/ 7n the-art. The

'r gld.- "aiid resistingsframewo'flk ,bf steel does not depend on' the adhesion o the concrete for its rigi dity;'- The vertical-and'horizontal anchoring b'ars'form a perfect. anchorage and serve to distribute the strain sfqually throughout the strilcture.

tend diagonally to the vertical barsfi, curvv g0. inplace of'the angle-bars 6 I show ilOOv 'Altho 'h'I have used the words horizontal and vertical.--I do not desire to limit myself b' these terms as they are used merely re atively' in regard to the angles of the two sets-of anchoringibjtrs, which angles may be varied from a ute o obtuse .as thevarious forms of stru ,turc demand.

2. reinforcedconcrete retaining wall comprising acurtaln Wall and a base slab, a

"framework of intersecting metal bars in said curtain wall, a framework of .intersectlng.

metal bars in said: base slab .detachahly connected to the framework in said curtain wall said slab framework from'said curtain wall ramework. i

3. A' reinforced concrete retaining wall comprising acurtain Wall and a base slab, a

framework of intersecting metal bars in said curtain wall, a framework of intersecting metalbars' in said base slab detach-ably connected to the framework in said curtain wall, bracing bars detachably secured to said slab framework and said curtain wall framework forbracing'one from the'other.

4. A reinforced concrete retaining wall comprising a curtain wall, a substantially herizontal bottom slab, counterfort members extending between and connectin curtain Wall and said slab, anchoring mem iers embedded in the said curtain wall and said slab at the intersection of the counterfeit members therewith, and reinforcing rods within said curtain wall and slab and tie-rods within the counterfort members detachably secured to said anchoring members.

A reinierced concrete retaining wall sisting surface, a base. slab integral with said curtain wall and extending rearwardly ofs'aid resisting surface, and concrete reinfore 'ennprising a curtain wall having a plane reing means at theangle of said wall and slab, 6. A reinforced concrete retaining wall comprising a curtain wall having a plane resisting surface, a base" slab integral with said curtain wall, reinforced concrete counter- .forts bracing the rear of said verticalwall from said base slab, andconcrete reinforcing means for bracing the angle of said wall and slab.
